[Rhyme]

Hey, all, I've been looking into building a decent desktop recently and came here for help. After a quick bit of researching, I came upon Marest's 750 build. With that all said, I come here asking for any additional help, tips, or comments to help round out the build. Thanks in advance!

Budget: $750-900
Resolution: 1080x720 or higher
Settings Desired: Good+ settings for WoW
Country: USA
Parts: From scratch
OS: Needed
Peripherals: Wireless keyboard wanted

Here's what I've gotten so far. (I'm completely new to this, so help is much appreciated): pcpartpi cker.c om/p/1nUmb

You wont be able to do much overclocking on the CPU with the stock heatsink, you might wanna grab a 212 EVO to keep the CPU cool.

I agree with Toffie's suggestion.

If your main concern is WoW, the i5-4670k is the best choice. As mentioned, get a better heatsink and overclock a bit for an even better boost.
If you want to save a few bucks, change the graphics card down one step (e.g. GTX 660). In WoW there should be basically little to no difference, as the games depends mostly on the cpu.

Resolution: 1080x720 or higher
Settings Desired: Good+ settings for WoW

I think you have something confused with the resolution. Either 720p (1280x720, this is what most games on PS3 or XBOX 360 run) or 1080p (1920x1080, most current monitors and TVs use this resolution). The "desired" resolution depends mostly on the monitor that you are going to use, because you should games (and windows that matter) with the "natural" (or full/maximum) resolution of said monitor/tv. Everything else will look very blurred.

But for WoW this doesn't really matter, as even a 1080p resolution at high/ultra settings can be handled by mid-range cards (~$150). If you only desire "good" settings for wow, you could easily go one step down to the "Gaming 570" build. This one will do WoW on 1080p with good/high setting without problems.
Toffie's suggestion is the maximum you will get out of WoW. You could literally dump another $1000 into the computer and probably only get 2-3fps more out of it.
